为了提高震级测定值的稳定性，保证资料产出质量，利用四川数字测震台网2008年10月—2012年4月间MS≥4.0近震记录，分析造成震级偏差的原因，并给出四川测震台网单台震级偏差分布特征。
In this article，the earthquakes MS≥4.0 in Sichuan province during the period from October 2008 to April 2012 were statistically studied，taking the average magnitude as standard magnitude，for analyzing the reason of magnitude deviation of the substations in Sichuan digital seismic network .Then they have gotten conclusions analyze the magnitude biases of stations and its influence on the final network＇s magnitude result that could server for researchers.
